3D printing is a nothing short of revolutionary. There may be no other technology that enables the at-home inventor or artist to design, create, and "print" their own parts, artwork, or whatever else can be imagined. Idiot's 3D Printing takes the true beginner through all of the steps necessary to design and build their own 3D printer and design and print whatever their imagination can conjure up (even another 3D printer). Readers will learn all of the essential basics of 3D printing including materials, parts, software, modeling, basic design, and finishing, and then teach them to take their new skills to the next level to print some simple, fun projects. For readers not interested in building their own 3D printer, there are tips and advice for buying a manufactured printer, buying materials, finding plans and projects online, and much, much more.
A good overview to the key points of 3D printers. To succeed you will obviously want to play around but it does get the key considerations covered to save some trial and error.
I would say this book has helped me manage expectations in what 3D printing can do.
